IncGamers has a list of skill changes the say should be part of the upcoming version 1.0.3 patch for Diablo III. They say these were mined from patch data found on Blizzard's servers, so this may still be subject to change. In some cases it is not actually the skill being changed, but simply the tooltip being updated to accurately reflect the skill. In other news related to the action/RPG sequel, the Diablo III Website features the recent Diablo III Developer "AMAA" Transcript.

These updates are server side only which negates the need to update the client. In theory this means less updates for the consumer. The issue is to update a tooltip the client needs to also be updated.
